ENDLESS THANKS to all who gave so much input and encouragement in the writing of this book-my editor, Michael V. Korda; his associate, senior editor Chuck Adams; my agent, Eugene H. Winick; Robert Ressler, Associate Director of Forensic Behavioral Services. Kudos to my daughter, Carol Higgins Clark, for her research, comments and suggestions and for burning the midnight oil with me as we raced to deadline. And of course, special thanks to the rest of my family and friends, who endured my usual self-doubting about whether or not I could tell this story; their saintly patience will have the cathedrals fighting for their bones.
